    I can only be speechless. It seems that Li Yuan is like a girl who fell in love for the first time. She fell in love with the flower picker who took away her virginity. She cuddles up to the window every day, stupidly and foolishly waiting for Li Mi.  The dark and obscene figure of this flower-picking thief appeared.  Of course, this description cannot be told to Li Shimin, so as not to save this kid from fighting me. However, Li Yuan acted like an unlucky ghost who was about to drown, and Li Mi stretched out a rope as thin as wool.  But Li Yuan could only reach out and grab it, hoping to survive.  My uncle finally left Jiaozhi, and Qiu He, the former prefect of Jiaozhi, has now become the governor of Jiaonan Province.  I have decreed that the three former counties of Jiaozhi, Jiuzhen, and Rinan and the surrounding areas will be merged into one province, and a large number of preferential policies will be given to vigorously develop the Jiaozhi area.  There is coal and iron here. Now, even nearly one-third of the steel in Guanzhong is imported from here.  The steel material is quite good, and the quality is stable. It is much better than the iron found in Guanzhong, which often had different impurities that would affect the quality of the steel.  Even now, the Artillery and Gunpowder Research Institute has set up two groups specifically to study the smelting of Cochin steel.  After all, the content and impurities of iron ore vary from place to place, and the required heat and methods of removing impurities are also different.  At present, Jiaozhi has developed to three shipyards and 35 large and medium-sized shipyards. The total number of workers has reached more than 17,000, and the number of people in related industries has exceeded 70,000.  The birth of cotton and the improvement of weaving machinery greatly improved the quality of sails.  Now, the No. 12 Dockyard of the largest Jiaozhi No. 1 Shipyard has begun to build the keel of a 653-ton giant ship. This is the largest ocean-going ship in the world today, and it is a condensed Fuzhou ship.  It is an excellent ship designed by improving the respective advantages of the three ships, Galen ship and clipper ship.  Named the Huaxia Ship, the ship only requires at least fifty people to operate it, and when fully loaded, it can carry up to a thousand people. Under normal circumstances, it can carry more than three hundred tons of cargo and two hundred and fifty people at sea.  Three months of non-stop sailing.  Such loading capacity and ocean-going performance are definitely second to none.  Moreover, the speed is not slow. Well, of course it is at least half slower than a real clipper ship, but compared to ordinary ships of this era, it is already extremely fast. The important thing is that this kind of ship  Its wind resistance is extremely strong, so it is very suitable for ocean sailing.  Previously, 100-ton and 200-ton ships of this design had already started sailing on the sea. After their verification and filling in the gaps, they finally decided to build this 653-ton giant ship.  Of course, this is far from the limit of ocean-going sailing ships. Remember that in later generations, the most powerful wooden battleship of the English Navy even reached two thousand tons, so we are still early.  In the future, I believe that we will have the ability and strength to build these warships in less than ten years.  " But whether to build it or not is another matter. After all, such a warship is indeed a sea fortress, but it needs a rival to match it before it can exert its huge power.  In this era, the largest ships are probably those of the Chinese Empire. Others, such as the Dashi and Persian warships, are said to have the largest ships of about one hundred tons. To deal with them, use two thousand tons of giant ships.  It really feels like killing a chicken with a big guillotine, which is inconsistent.  Nowadays, the ships produced by the shipyards in Cochin are gradually replacing the merchant ships in the hands of the Chinese Empire's maritime merchants. However, if you want to buy our merchant ships, there is no problem, but these ships have clear numbers.  , and will make it clear to these merchants that these ships must not be sold to anyone outside the Chinese Empire.  Although it is not possible to completely prohibit other countries from learning the technology, the sooner the better. In addition, currently only Fuchuan, Shaban and Galen ships are sold as merchant ships, while clipper ships and Huaxia ships are not allowed to sell to merchant ships.  Sold by anyone.  And their production is also limited to the No. 1 Shipyard, which is a standard military shipyard. Anyone who dares to get close will go to prison and eat for a few years.  The total population of Jiaozhi is also expanding rapidly. From less than 180,000 in the past, it has now exceeded 350,000. There are enough people coming to Jiaozhi from Tiannan to work in the shipbuilding industry and related industries.  One hundred thousand people.  Although gunpowder weapons have begun to be used in large quantities, at present, the gunpowder weapons production factory is still kept secret and has been arranged by me at the foot of the mountain in the north of Qinling Mountains. At present, the most produced items are grenades or landmines.  ??A grenade only needs to be wrapped with a layer of properly tempered iron sheet with beautiful patterns on the outside, and the inside is naturally filled with granular gunpowder. In addition, its ignition equipment is the simplest, a flint ignition device.  There is no need for any high-tech and sophisticated gadgets, or even too sophisticated parts. Even the outsourced iron sheet is just iron sheet. Therefore, the hand??This kind of high-quality and low-priced stuff has become a stuff that the generals strive for.  At present, it is mainly supplied to the armies in places like Yan'an County, Xihai County, Heyuan County, or south of Bashu. Well, it is the best weapon to use to frighten foreign enemies.  On the contrary, it is rarely used in civil wars.  As for the artillery, we are still making preparations. In a word, if there is not enough copper, how can we make the artillery?  The flintlock muskets are now equipped with a guard battalion and are expected to be equipped with a division by the end of this year. By that time, the world's first gunpowder weapons unit in history will be unveiled to the world.  Show your true face.  In addition, the research and smelting work of cast iron is currently progressing by leaps and bounds.  Today's Chinese Empire is short of copper, but there is no shortage of steel. What's more, the high-quality steel shipped from Cochin is very popular among craftsmen.  When there was a copper shortage before, the smelting and improvement of cast iron was already on the agenda, but progress was very slow.  The most important thing is that the performance of cast iron cannons is indeed inferior to cannons cast from bronze and brass. The advantage of cast iron is that it is cheap, not that its performance is better than other metals.  Whether it is brass or bronze, although it is expensive, it is tough and not easy to burst.  The bronze cannon will deform after being fired for a long time, which will interfere with the passage of the cannonball through the barrel.  Therefore, the best artillery shot is still brass.  However, cast iron can be improved. The earliest cast iron cannons would explode after firing five shells in a row, while later cast iron cannons could already fire twenty-five to thirty shells without exploding the barrels.  Nowadays, the quality of the cast iron produced is quite good, but there are still some problems that need to be solved. For example, the strength is still slightly insufficient, and continuous firing will still cause the chamber to explode. In addition, the cast shell of the cast gun still needs to be improved.  , and the quality of molten iron in cast iron still has the possibility to be improved.  That is to try to reduce the impurities and carbon content in the cast iron molten iron.  ¡°If it is really possible to significantly reduce the impurities and carbon content, perhaps high-quality things like cast steel will appear nearly a thousand years in advance.  Think about it during the First World War, the cast steel artillery of Germany's Krupp Company could be said to be the top artillery of that era.  And now we have coke, plus what I proposed to them is to blow in hot air to accelerate the oxidation of impurities in the iron water. In addition, we add lime, fluorite, and bauxite to filter out some useless phosphorus and other impurities to form waste residue.  .  It is now possible to refine better steel. Unfortunately, with my poor chemistry knowledge, I only know that oxygen can be obtained through electrolysis. I really don¡¯t know how to work to extract oxygen.  Even these smelting methods are some basic common sense that I asked after seeing them in the small steel plants in the town.  Nowadays, I just turn a blind eye to the issues discussed by those old craftsmen. At most, I can only occasionally squeak to express my support and encouragement to them.  "I am very fortunate that these people have learned to use pens and record every research process, so that newcomers who join later can understand the principles and methods of steel smelting in the shortest possible time.  Even many of the textbooks in the Institute of Engineering in the college today are for these old craftsmen who have not been able to read for most of their lives. They first learned to read and write, and then wrote down their own experiences, or hired people to record their experiences.  Ideas and ideas, finally obtained.  As long as this problem can be solved, I believe that in the near future, the Chinese Empire's army will be able to use cast steel artillery. By then, copper will only be used to cast artillery shells, which can save a lot of copper.  materials to do other things.  The North, East Turks, and Jieli Khan once again sent envoys, strongly urging us to increase the exchange ratio of spirits and horses, strongly urging us to open the export of iron tools, and even requested that they hope to conduct arms trade with us and are willing to use  Horses, cattle, sheep and other materials they owned were exchanged for weapons and armor produced by the Chinese Empire.  Nowadays, Bailian weapons have begun to be equipped in large-scale troops. Although the lethality of Bailian steel sword is not enough to cut off the enemy's weapon with one knife, it can easily break through the opponent's armor.  Especially leather armor. In front of the steel-making knife, leather armor is not much different from paper.  Even if it is iron armor, a powerful person like Li Yuanfang can easily cut through the iron armor using a hundred steel swords.  Now, we have sold out all the inventory in the Chang'an weapons arsenal of the original Sui Dynasty. Well, we can either use it as a favor or sell it to those powerful people who need it, especially those from the Central Plains.  Even thirty-refined weapons have begun to be exported, of course, not to the grasslands, but to powerful powers who are in urgent need of weapons but cannot satisfy their own production.  Our navy now allows our merchants to freely reach any powerful territory to conduct trade.
